, ".i." v il Toi/7Mgio/'muret 211.1111/ oonwr/i .Stute ol? `illinois, have invented Certain new and juse'tnl.. improvements in l reptaolertllosures, of which the following is Locks for 'Re afgis]rel-iliealxiou. reference heine' had to tho accompanying drawings.

."llhisinvention relates looks Vtor lreeel'ataele closures, und has for its primary iiihjeot to provide` a simple and ellieientfdevii-effor lot-king` raps upon automo- 'hile radiators, fuel storage tanks and in all other instances where a (levier, ot this Character may he `Found desirable.

The invention has i'or anolhe and more spel-ille ohjet-t. tht` provision of a trap or closure for tho filling;- opening' of the tank or reservrgiir which is prtn'ided with an annular series ot rack teeth, and a lock secured upon the. tubular lillinp;` nipple or ext-e sion ol' the, tank or reservoir including a spring pressed loeking holt to engage the annular series of rack teeth when the cap is thr ,aded to its closed position and prevent reverse movement of the cap.

The, invention has for a 'further object. the provision ot improved means Vforattiurhingr the lock lo the tilting nipple.

lith the ahove and other ohjeets in view as will heeolno apparent as' the description proeeeds, theinventitm consists in eertain eonstruotimis, combinations and arrange-V ments of the parts that t shall hereinafter fully describe and claim.

For a full understanding;I of the invention, reforouce is to he had to the 'following description und accompanying drawings, in wh i ol 1- Figure 1 is a side elevation showing a rap looked upon the filling nipple ot' an aulonio bile radiator by moans ot' the present inventimn; Fig. 2 is a seetion taken on the line 2m? of Fig. l; Fig. 3 is a see-lion taken on the, line 3-3 of Fig. l.

Referringr in detail, to tho drawing, 5 design-rites n portion ot' an :uitoinohile radiator, although it is to he understood that the pres` ont invention is applicable as well to gasoilone storage, tanks and other reoeptaeles, The tank or radiator is provided with the usual filling extension or nipple t3, having n reduced exteriorly threaded upper end 7. The closure rap 8 'for the fillingf nipple, may he -oil any preferred 4forni und includes a to improvements inI Application tledMay 21. 1913. Serial No. 769,107.

hotly which is reduced in thickness atits.`

edge to 'forni .un annular (lange :1nd n shoulder 1t) at, the .inner ond ot said flange.

` l'his shoulder is provided'willrteeth 'tit facing"y in a dirert-ion opposite. lo that in whieh the oap is'turned when it threaded to its rlosrd posit-ion upon the nipple flexible metal hand lf2 surrouni'ls the nipple (5 adjnoent Athe, threaded portion 7 thereof and at one of its ends is fastened by means of a rorew l-Tto Suid nipple. 'lho' look easing lll is provided upon opposite ends with the loops l5 through whirhhe ex tieruities of t 1e metal hand li are disposed. (hie end of the hand is returned upon itself a'l`tor being passed through one ot the loops lf: and inserti-d through a metal loop lliurrangeil upon the hand. This loop lt' is held against shifting' inmi'fnnent'hv means ol `tho sert-ws 11T which have tln'eaded engagement in openings provided in the hand. .'lhese srrews are arranged upon opposite Sides of the loop 1li. Thus the end ot the, hand will he ell'eetually retained in connection with thev loop 15 on the loflt' easingxll. rthe look easing l-l is preterahly ol` rectangular l'orin and`within the saine, a loc-king holt It] is arranged, said holt lining` niovahle through au opt-ning,y in the upper wall of the look easing and between one of thel end walls thereof' and u lguide plate l5). -'l`he inner lowerend o'l this looking;- holt l s a lug Edt) tol-ined thereon, und a ooil spring Z1 is ai ranged in the cardine,T and hears against the lower end of the loeking holt to normally toree the saine upwardly.

i .22 designates un opening in the front Vall ol' the lock easing' to receive a suitahle key, which when turned engages the. lug Q() olI the looking;` holt as shown in dotted lines in Fig. l to torre said holt downwardly and release the rap so it can he removed from the llling' nipple. or extension of the tank or reservoir. i

l `ron1 the ahove desoriptioin the operation olf the. invention will he obvious. As the rlosure rap S istln'oaded downwardly upon the upper end ot' the tilling nipple, the an nnlar-series ol rack teeth 1l thereolf' engage the upper end of tho looking holt .it and ride over the saine, Said holt being gradually Forced downwardly against the notion of the spring 2h lt will thus he apparent that when the rap has heen threaded to its closed position, the end of the holt hearing against one ot' the teeth ll will ell'eotually prevent that it cannot be removed from the nipple.'v

Unauthorized persons are therefore preventi ed from obtaining aecefs to the interior of dorstood that by providing the band 12 for the tank or reservoir while at the'seme time, the cap may be readily removed by the' possessor ol the key. through the opening 2Q of the lock easing, it is only necessary to turn the same to canse the wing or iangeof the key to bear against the lug 20 and force the looking boli'l dowmvardly to its release position whereby the. closure'lca'p may be easily and quickly Unthreaded and removed from' the upper end ol' the nipple 6.

From ihe foregoing, it is' thought that the construetion and operation of the invention will be clearly understood. It will be unattaehi'ng the'loek easing'to the filling extension or nipple of the tank or reservoir, it is only necessary to secure said band to the wall of the ni ple at one of its ends, the other end lof tie band being connected' to 1he loi-,k easingI in the manner above de- L-'eribed. It will however-be .appreciated that instead ofeniploying this band7 the lock casing might be otherwise attached to the After inserting the key filling nipple or extension of the' tank if desired. It Will 'further be obvious 'that my invention is capable of many minor modificatlonsln the form,' proportion and artures thereof or sacrificing .any of the advantages of thedevlce as Claimed.

Having thus described'the',invention, what is claimed is:

. The combination,Withatank or reservoir' Y 40 i' .said nipple provlded with an annular series l u l f of rack teeth, and an ann'uler'tlange on said having a filling nipple, of a closure. cap 'for rack teeth, and a look secured upon the llf ing nipple ineludin a'locking bolt adapted I to extend betweenv t e flange ofthecap andV the nipple und engage with saidv rack teeth,

when the cap is threaded to its closedposition to prevent reverse turningmovement-of the cap.

In testimony whereof hereunto aiiix my signature in the presence of two witnesses.
